Yeelight Color LED Bulb... issues on issues on issues

After attempting to upgrade the firmware, it seems like I have lost total control of both the bulbs I got. Now simply turning on the lamp, it starts to flash white 5 times, followed by cycling through all colors, then flash white 5 times, followed by cycling through all colors.

Resetting it by doing the 2 seconds on and 2 seconds off 5 times is not helping anymore.


What voltage do you use? Does it match the bulb?

No, I’m in Canada and on 110V while I got 220V bulbs from AliExpress.

Which one do you have? Could you post a link?

I can’t access the link, please give me the product page.

sorry, I believe this will work then:,searchweb201602_4_10065_10068_10130_10547_10059_5726812_10884_10548_10887_10696_100031_10084_10083_10103_5726912_10618_10139_10307,searchweb201603_60,ppcSwitch_0&algo_expid=d3db3d17-00b0-4ee2-bb8d-a66f95ff3838-0&algo_pvid=d3db3d17-00b0-4ee2-bb8d-a66f95ff3838&priceBeautifyAB=0

That’s it, this bulb is our v1 version, 220v ~ 240v support only.

You can choose v2 version, which is wide voltage support, 110v ~ 240v.,searchweb201602_3_10065_10068_5726815_10546_10059_10884_10548_10887_10696_100031_10084_10083_5726915_10103_10618_10307_449,searchweb201603_60,ppcSwitch_0&algo_expid=6ab18e10-8271-48e1-99d9-c5d31d31bd26-1&algo_pvid=6ab18e10-8271-48e1-99d9-c5d31d31bd26&priceBeautifyAB=0
